Young scholars conduct a series of experiments on electromagnets. In this physics lesson, students build their own electromagnet and explain how it works. They determine the factors that affect its strength.

Students construct a homopolar motor following certain procedures. In this physics lesson, students explain how generators and motors work. They compare and contrast the characteristics of both.

Students build simple electromagnetic reed switch motors. In this physics lesson, students explain how it works. They cite real world applications of reed switches and relays.

Students compare a stepper motor from a traditional motor. In this physics instructional activity, students summarize how it works. They build their own stepper motor and explore its uses.

Students conduct a series of experiments on thermoelectricity. In this physics lesson, students investigate how thermocouple works. They determine the voltage generated when different conductive materials are held at different temperatures.

Physics fanatics time five cars as they pass on the highway. They use the times and a 20-yard distance to calculate velocity. They also graph distance vs. time. A page of student pre-lab questions is provided in addition to the activity...

Students comprehend what makes up the physical community. Read and construct scale drawings and models. Explore the history of infrastructures and how the contributions of science, math and industry have led to the development of their...

Arranged as an interactive lesson, this presentation focuses on the six world biomes. Upcoming biologists click on a specific biome and a slide lists its location, description, native plants, and animals. A quiz provides learners with...

Using maps, images, websites, and handouts, learners work to understand the nature of human migrations. They compare and contrast human migration from the past to the present, identify causes for migration, and trace migration routes on...

With the global temperature on the rise, the effects of climate change are starting to be seen. However, many people have a difficult time conceptualizing the long-term effects, such as sea levels rising. Given an easy and effective...

From gas to liquid condensation to solid frost, water undergoes phase changes before students' eyes! Using ice, salt, water, and a metal can, they set up an investigation that can be used in a physical science setting, or as part of a...

Not many youngsters realize that solids aren't the only materials that can possibly be dissolved in water. During this investigation, they find out that some liquids can dissolve in water as well. This is part of a unit on solubility,...

By both demonstration and hands-on investigation, physical science fanatics come to know that some materials react when they come together. Adding vinegar to both baking soda and to baking powder, the difference between the two is clear....

When Einstein first heard the theory of the expanding universe, he dismissed it as bad physics. Now scholars learn about the theory and how scientists prove it has merit. Through a hands-on simulation and videos, class members measure...

Ancient people used musical pipes as early as the third millennium BCE. Young scientists explore the workings of musical pipes to better understand the relationship with frequency, length of pipe, and sound waves. They determine the...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...
